Revision that works
How many hours a day should I revise?
In term time, one to two focused hours a day on top of homework is plenty for most students. In the holidays and exam season, three to four hours split into short sessions with proper breaks is a strong day. Past about five hours, most people are rereading rather than learning - how you revise matters far more than how long.

The honest numbers
There is no magic figure, but there is a sensible range - and it is smaller than the scary numbers people post online.
| When | A good day looks like |
|---|---|
| Term time (exams months away) | 1–2 focused hours on top of homework |
| Half term / Easter holidays | 2–4 hours, split into 25–40 minute sessions |
| Study leave / exam season | 3–5 hours around your timetable, with real breaks |
| The night before a paper | Light review only, then stop - sleep is worth more |
Why more hours stops working
Learning happens when your brain retrieves - pulls an answer out under its own steam. Retrieval is tiring, and after a few focused hours the quality collapses: you drift into rereading and highlighting, which feel like work but change very little. Two sharp hours of answering questions beat six foggy hours of turning pages, every time.
Breaks are part of the method, not a guilty pause in it. A short walk, food, or half an hour completely off lets the next session actually count.
Someone online says they do eight hours a day
Someone online always does. Hour-counts posted on forums are unverifiable, usually exaggerated, and even when true they mostly describe time at a desk, not time learning. Comparing your revision to a stranger's numbers is a fast route to feeling behind while learning nothing new. Measure the only thing that matters: can you answer questions today that you could not answer last week?
How to tell your hours are working
Test, don't trust. End each session by answering two or three questions from memory. If you can, the session worked. If you can't, the fix is not a longer session tomorrow - it is a different method: fewer notes, more questions.
